Cellular cushioning material and a method for its production is described. In one scenario, the method includes providing a pre-welded sheet to a user comprised of at least two layers of plastic pre-welded to have a plurality of diagonally oriented, inflatable sleeves (10) extending substantially the entire width of said sheet, and a longitudinally extending air entry passage (14). Each of the inflatable sleeves has an opening for allowing entry of air from said air entry passage into said sleeve. The user inflates the cellular cushioning material on an as-needed, real-time basis.
L'invention concerne un matériau de calage cellulaire et un procédé de production correspondant. Dans une réalisation, le procédé consiste à mettre, à disposition d'un utilisateur, une feuille déjà soudée comprenant deux couches, au moins, de plastique préalablement soudées possédant de nombreux manchons gonflables, orientés en diagonale, s'étendant sensiblement sur toute la largeur de la feuille, avec un passage d'entrée d'air disposé longitudinalement. Chaque manchon gonflable possède un orifice permettant l'introduction d'air, dans le manchon, provenant du passage d'entrée d'air. L'utilisateur gonfle le matériau de calage cellulaire, en temps réel, selon ses besoins.
